[0022] The process of a terminal device searching for a cell is divided into two steps: First, the first SSB is searched on the first downlink frequency domain unit set corresponding to a small set of candidate frequency points (e.g., the GSCN set). After finding the first SSB, cell access assistance information is obtained based on the first SSB. Then, based on the cell access assistance information, the second SSB is received or downlink control information is listened to on the corresponding second downlink frequency domain unit set to obtain the cell's system messages. When the network device enters energy-saving mode (e.g., when the number of terminal devices in the cell is small or the service load is light), the transmission of "always-on" signals on the second downlink frequency domain unit set can be reduced or not, avoiding meaningless energy consumption. When a terminal device needs to receive an "always-on" signal (e.g., when the terminal device needs to receive the cell's system messages), it can send WUS to the network device through uplink WUS resources to request the network device to send an "always-on" signal, which can save network energy consumption and ensure the access performance of the terminal device.

[0048] Please refer to Figure 1, which shows a schematic diagram of a network architecture 100 provided in one embodiment of this application. The network architecture 100 may include: a terminal device 10, an access network device 20, and a core network element 30.

[0049] Terminal device 10 can refer to UE (User Equipment), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, user agent, or user equipment. In some embodiments, terminal device 10 can also be a cellular phone, cordless phone, SIP (Session Initiation Protocol) phone, WLL (Wireless Local Loop) station, PDA (Personal Digital Assistant), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in 5GS (5th Generation System), or terminal device in the future evolved PLMN (Public Land Mobile Network), etc., and this application embodiment is not limited thereto. For ease of description, the devices mentioned above are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed within the cell managed by each access network device 20. Terminal equipment can also be simply referred to as terminal or UE, the meaning of which can be understood by those skilled in the art.

[0050] Access network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal device 10. Access network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with access network device functionality may differ; for example, in a 5G NR system, it is called gNodeB or gNB. As communication technologies evolve, the name "access network device" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 10 are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between terminal device 10 and core network element 30 through access network device 20. For example, in an LTE (Long Term Evolution) system, access network device 20 may be one or more eNodeBs in an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or EUTRAN; in a 5G NR system, access network device 20 may be one or more gNBs in a RAN (Radio Access Network). In the embodiments of this application, unless otherwise specified, the term "network device" refers to access network device 20, such as a base station.

[0051] Core network element 30 is a network element deployed in the core network. Its main functions are to provide user connectivity, manage users, and bear services, serving as an interface to external networks. For example, core network elements in a 5G NR system may include AMF (Access and Mobility Management Function) entities, UPF (User Plane Function) entities, and SMF (Session Management Function) entities.

[0052] In some embodiments, the access network device 20 and the core network element 30 communicate with each other via some air interface technology, such as the NG interface in a 5G NR system. The access network device 20 and the terminal device 10 communicate with each other via some air interface technology, such as the Uu interface.

[0053] The "5G NR system" in this application embodiment can also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in this application embodiment can be applied to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (such as B5G (Beyond 5G, a fifth-generation mobile communication technology) systems, 6G systems (6th Generation System, a sixth-generation mobile communication system)), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems. This application does not limit these applications.

[0054] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0055] The following section introduces and explains the background of network energy saving, the initial access process in the NR system, and fragment spectrum aggregation. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0056] 1. Background of Network Energy Conservation

[0057] Network energy saving (NES) is of great significance for environmental sustainability, reducing environmental impact (reducing greenhouse gas emissions), and saving operating costs. Energy consumption has become a key part of operators' operating expenditure (OPEX). According to a report by the GSMA (Global System for Mobile Communications Association), energy costs of mobile networks account for approximately 23% of total operating costs. Most of the energy consumption comes from the radio access network, more specifically from the active antenna unit (AAU), with data centers and fiber optic transmission accounting for a smaller share. The power consumption of a single radio access can be divided into two parts: the dynamic part includes only the power consumption when data is being transmitted or received; the static part includes the power consumption at all times for the necessary operation of the radio access equipment, including the power consumption when no data is being transmitted or received.

[0058] With the development of communication technology and the evolution of communication systems, energy consumption has gradually become an important KPI (Key Performance Indicator) for the operating efficiency of communication systems. Therefore, when designing 6G communication systems, network energy-saving technologies need to be considered from the very first version.

[0059] 2. Initial Access Procedure in NR System

[0060] In NR systems, the initial access process for terminal devices can be completed by detecting synchronization signal blocks (SSBs or SS / PBCH blocks) on the GSCN (Global Synchronization Channel Number) (also known as the Sync Raster). During the initial access process, the terminal device determines the possible time-frequency locations of SSBs using a predefined set of GSCNs, attempts to search for SSBs, and obtains time and frequency synchronization, radio frame timing, and cell IDs (identifiers) through the detected SSBs.

[0061] After detecting an SSB, the terminal device can determine the configuration of the Type0-PDCCH (Physical Downlink Control Channel) CSS (Common Search Space) set through the MIB (Master Information Block) message in the SSB. The terminal device can receive the network device's scheduling of SIB1 (System Information Block) messages by listening to the Type0-PDCCH CSS set. Both the MIB and SIB1 messages include the serving cell's system configuration information. Furthermore, the terminal device can receive the network device's scheduling of other system messages besides SIB1 messages by listening to the Type0A-PDCCH CSS set, receive the network device's scheduling of paging messages by listening to the Type2-PDCCH CSS set, and receive the Paging Early Indication (PEI) information for paging messages sent by the network device by listening to the Type2A-PDCCH CSS set.

[0062] The terminal device can also obtain the resource configuration of PRACH (Physical Random Access Channel) transmission opportunities (RO) during the random access process based on the received system message SIB1 from the cell. Based on the RO resources configured by the network device, the terminal device can initiate random access to the network device or request the sending of system messages.

[0063] 3. Fragmented Spectrum Aggregation

[0064] In low-frequency bands across different countries or regions, multiple fragmented spectrum block resources exist, as shown in Figure 2. In Figure 2, identical fills indicate spectrum used by the same operator, and each block represents a spectrum size of 5MHz. The first row of Figure 2 shows the spectrum block resources of multiple fragments corresponding to PCS (Personal Communications Service). The second row shows the spectrum block resources of multiple fragments corresponding to BRS (Broadband Radio Service). The third row shows the spectrum block resources of multiple fragments corresponding to AWS (Advanced Wireless Service). Each fragmented spectrum block can be viewed as a CC (Component Carrier), meaning one CC corresponds to a continuous segment of spectrum resources.

[0065] In NR system deployment, each carrier cluster (CC) is networked as a cell. In NR systems, the number of radio frequency chains (RF chains) supported by terminal devices is limited and unlikely to increase significantly. Since each CC requires an independent RF link, the data transmission rate of the terminal device is limited by the number of CCs supporting carrier aggregation (CA). To utilize the spectrum resources of multiple fragments in low-frequency bands, NR systems have begun to explore the scenario of multiple carriers sharing a single RF link. For example, for multiple CCs in a single downlink band with a frequency range of less than or equal to 100MHz, RF link sharing can be used for data transmission. This allows the terminal device to support data transmission with the same bandwidth as before using fewer RF links, thereby enabling the terminal device to support data transmission with a larger bandwidth without increasing the number of RF links, thus improving the data transmission rate. When designing future wireless communication systems, such as 6G communication systems, it is also necessary to consider the fragment spectrum aggregation feature to design a wireless communication system that rationally utilizes this spectrum aggregation characteristic. For example, in a 6G communication system, a cell may include the resources of multiple CCs, or multiple CCs are networked as a single cell.

[0066] With the development of communication technology, research on 6G communication technology has begun. Considering the importance of network energy saving, possible network energy-saving solutions need to be considered from the initial design stage of 6G communication technology. From the perspective of network energy saving, network equipment should minimize the transmission of "always-on" signals (such as SSB, SIB, paging, etc.) to avoid potentially meaningless energy consumption.

[0067] It should be understood that the technical solutions provided in the embodiments of this application can be applied to a scenario where a cell includes multiple CCs, or to a scenario where a cell includes one CC.

[0068] Please refer to Figure 3, which shows a flowchart of a wireless communication method provided in one embodiment of this application. This method can be applied to the network architecture shown in Figure 1. The method may include at least one of the following steps 310-320.

[0069] Step 310: The terminal device receives a first system message based on the first SSB received in the first downlink frequency domain unit set, wherein the first SSB is used to receive the first system message.

[0070] Step 320: The terminal device obtains first WUS configuration information based on the first system message, wherein the first system message is used to determine the first WUS configuration information, the first WUS configuration information is used to determine the first WUS resource in the first uplink frequency domain unit set, and the first WUS resource is used to transmit the first WUS.

[0071] In some embodiments, the first downlink frequency domain unit set is a set of downlink frequency domain units used for transmitting and receiving a first SSB. In some embodiments, the first downlink frequency domain unit set is a set of downlink frequency domain units used for transmitting and receiving a first SSB and a first system message. In some embodiments, the first downlink frequency domain unit set is a set of downlink frequency domain units used for transmitting and receiving a first SSB and N system messages, where the N system messages include the first system message, and N is a positive integer.

[0072] In some embodiments, the downlink frequency domain unit set is a set of frequency domain units used for downlink transmission. The frequency domain unit set includes one or more frequency domain units. A frequency domain unit can be understood as a partitioning unit of frequency domain resources. Optionally, a frequency domain unit is an RB (Resource Block) or a portion of bandwidth. The downlink frequency domain unit set includes one or more downlink frequency domain units, which are frequency domain units used for downlink transmission.

[0073] In some embodiments, the network device transmits a first SSB in a first downlink frequency domain unit set. The first SSB is used to receive N system messages, including the first system message, where N is a positive integer. In this case, one SSB transmitted by the network device can be used to receive N system messages. For example, if the SSB transmission opportunity corresponding to the first SSB transmitted by the network device includes two SSBs, then each of the two SSBs can be used to receive N system messages. As another example, if the SSB transmission opportunity corresponding to the first SSB transmitted by the network device includes two SSBs, then the first SSB of the two SSBs can be used to receive N system messages, and the other SSB of the two SSBs can be used to receive one system message.

[0074] In some embodiments, the network device transmits N SSBs in a first downlink frequency domain unit set. Each of the N SSBs is used to receive one system message from N system messages. The first SSB among the N SSBs is used to receive the first system message from the N system messages, where N is a positive integer. In this case, the network device transmits N SSBs, which correspond one-to-one with the N system messages. One SSB is used to receive the system message corresponding to that SSB. The value of N can be equal to 1 or greater than 1. The first SSB is one of the N SSBs, and this first SSB is used to receive the first system message from the N system messages. The first system message is the system message corresponding to the first SSB among the N system messages.

[0075] In some embodiments, a first system message is used to determine first WUS configuration information, including: N system messages used to determine N WUS configuration information, wherein each of the N system messages is used to determine one WUS configuration information, and the first system message is used to determine the first WUS configuration information, where N is a positive integer. For example, the network device sends a first SSB in a first downlink frequency domain unit set, and the first SSB is used to receive N system messages; or, the network device sends N SSBs in the first downlink frequency domain unit set, and each of the N SSBs is used to receive one of the N system messages. For the aforementioned N system messages, there is a one-to-one correspondence between the N system messages and the N WUS configuration information, and each system message is used to determine one WUS configuration information. For example, the N system messages include system message #1 and system message #2, where system message #1 is used to determine the first WUS configuration information, and system message #2 is used to determine the second WUS configuration information; wherein system message #1 and system message #2 are two different system messages, and the first WUS configuration information and the second WUS configuration information are two different WUS configuration information.

[0076] In some embodiments, the first system message is used to determine N WUS configuration information, where the N WUS configuration information includes the first WUS configuration information, and N is a positive integer. For example, the network device transmits a first SSB in a first downlink frequency domain unit set. The first SSB is used to receive the first system message, which is used to determine the N WUS configuration information. For instance, the first system message is used to determine two WUS configuration information, which includes the first WUS configuration information and the second WUS configuration information.

[0081] In some embodiments, a particular set of functions or capabilities includes at least one of the following: receive bandwidth, transmit bandwidth, receive antenna, transmit antenna, number of receive ports, number of transmit ports, number of transmit layers, maximum supported MCS (Modulation and Coding Scheme), maximum data rate, massive MIMO (Multiple Input Multiple Output), millimeter wave, SBFD (Subband non-overlapping Full Duplex), unlicensed spectrum, positioning, low power consumption, multi-carrier, and IAB (Integrated Access Backhaul).

[0082] For example, the aforementioned N WUS configuration information pieces include WUS configuration information specific to a particular function or capability set. For instance, the aforementioned N WUS configuration information pieces include first WUS configuration information and second WUS configuration information. Optionally, the first WUS configuration information is WUS configuration information for a first function or capability set, and the second WUS configuration information is WUS configuration information for a second function or capability set; the first function or capability set and the second function or capability set are two different function or capability sets. Optionally, the first WUS configuration information is WUS configuration information for a first function or capability set, and the second WUS configuration information is a system message that is not part of the first function or capability set; a non-first function or capability set refers to other function or capability sets besides the first function or capability set.

[0083] For example, the first set of functions or capabilities may also be referred to as a small function core or a small core. For example, a small core may refer to: the terminal device receiving or transmitting signals through the first set of UE functions / capabilities, or the terminal device receiving / transmitting a first set of signals, or the terminal device receiving / transmitting signals within a first set of resources, or the terminal device receiving / transmitting signals through a small function core.

[0084] For example, the second set of functions or capabilities may also be referred to as a large functional core or a large core.

[0085] Optionally, at least one function / capability in the second set of functions or capabilities differs from the first set of functions or capabilities, such as maximum receive or transmit bandwidth; the time-frequency resources occupied by the second set of signals, or the time-frequency resources contained in the second set of resources differ from the first set of signals / resources.

[0086] Optionally, the same terminal device can switch between a first set of functions or capabilities and a second set of functions or capabilities, or support only the first set of functions or capabilities; the same terminal device can receive / transmit different sets of signals at different times, or receive / transmit only the first set of signals; the same terminal device can receive / transmit signals in different resource sets at different times, or receive / transmit signals only within the first resource set.

[0087] Optionally, the non-first set of functions or capabilities includes: the terminal device receiving or transmitting signals through capabilities or functions beyond the first set of functions or capabilities; or the terminal device receiving / transmitting signals outside the first set of signals; or the terminal device receiving / transmitting signals within resources outside the first set of resources.

[0099] For example, the aforementioned N WUS configuration information includes WUS configuration information dedicated to a specific channel or signal of a specific cell. For instance, the aforementioned N WUS configuration information includes first WUS configuration information and second WUS configuration information. The first WUS configuration information is the WUS configuration information requesting the network device to transmit the SSB of the first cell, and the second WUS configuration information is the WUS configuration information requesting the network device to transmit the second system message of the second cell. Here, the first cell and the second cell are two different cells.

When the first SSB and the N WUS configuration information sets correspond to the same cell, the first SSB, WUS configuration information #1, WUS configuration information #2, and WUS configuration information #3 correspond to the same cell. When the first SSB and the N WUS configuration information sets correspond to different cells, the first SSB, WUS configuration information #1, WUS configuration information #2, and WUS configuration information #3 correspond to different cells. In cases where a portion of the first SSB and the N WUS configuration information sets correspond to the same cell, and another portion of the first SSB and the N WUS configuration information sets correspond to different cells, for example, the first SSB and WUS configuration information #1 correspond to the same cell, while the first SSB, WUS configuration information #2, and WUS configuration information #3 correspond to different cells.

[0102] In some embodiments, when N is greater than 1, the relationship between the N WUS configuration information includes one of the following: the N WUS configuration information correspond to the same cell; or, the N WUS configuration information correspond to different cells; or, a portion of the N WUS configuration information corresponds to the same cell, and another portion of the N WUS configuration information corresponds to different cells.

[0107] Optionally, different frequency domain unit sets refer to: when the transmission directions of the frequency domain unit sets are the same (e.g., all are downlink, or all are uplink, or all are TDD), at least two of the three parameters—start position, end position, and number of frequency domain units—are different; or, the transmission directions of the frequency domain unit sets are different.

[0108] The first SSB will be introduced below.

[0109] In some embodiments, the first SSB is used to receive a first system message, including one of the following (1) to (4).

[0110] (1) The first SSB carries the first system message.

[0111] For example, the first system message is carried in the PBCH (Physical Broadcast Channel) of the first SSB.

[0112] For example, the first SSB carries N system messages, including the first system message, where N is a positive integer.

[0113] For example, the PBCH of the first SSB carries N system messages.

[0114] In some embodiments, the first SSB is used to determine the first time-frequency resource, which is used to receive the first system message, including any one of the following (2) to (4).

[0115] For example, the first SSB of different indices can be used to determine different first system messages.

[0116] (2) The first SSB is used to determine the first time-frequency resource, which is used to transmit the PDSCH (Physical Downlink Shared Channel) carrying the first system message.

[0117] For example, the first time-frequency resource is used to transmit a first PDSCH, which carries a first system message.

[0118] For example, the first time-frequency resource is used to transmit the first PDSCH, which carries N system messages, including the first system message, where N is a positive integer.

[0120] (3) The first SSB is used to determine the first time-frequency resource, which is used to transmit the PDCCH carrying the first system message.

[0121] For example, the first time-frequency resource is used to transmit a first PDCCH, which carries a first system message.

[0122] For example, the first time-frequency resource is used to transmit the first PDCCH, which carries N system messages, including the first system message, where N is a positive integer.

[0124] (4) The first SSB is used to determine the first time-frequency resource, and the first time-frequency resource is used to transmit the PDCCH carrying the first system message of the PDSCH.

[0125] For example, the first time-frequency resource is used to transmit the second PDCCH, the second PDCCH is used to schedule the second PDSCH, and the second PDSCH carries the first system message.

[0126] For example, the first time-frequency resource is used to transmit the second PDCCH, the second PDCCH is used to schedule the second PDSCH, the second PDSCH carries N system messages, the N system messages include the first system message, and N is a positive integer.

[0127] For example, as shown in FIG6, the first SSB is used to determine the first time-frequency resource, the first time-frequency resource is used to transmit the second PDCCH, the second PDCCH is used to schedule the second PDSCH, and the second PDSCH carries N system messages, including the first system message, where N is a positive integer.

[0128] In some embodiments, the first SSB is used to determine the first time-frequency resource, including both explicit and implicit determination methods. Optionally, the first SSB is used to determine the first time-frequency resource, including at least one of the following (1) to (3).

[0129] (1) The first SSB carries indication information for determining the first time-frequency resource.

[0130] For example, the bandwidth occupied by the first SSB (i.e., the first downlink frequency domain unit set) is preset, and the bandwidth occupied by the first SSB is the same as the downlink bandwidth corresponding to the first SSB (e.g., the starting position and bandwidth size are the same). The first time-frequency resource is the time-frequency resource in the downlink bandwidth corresponding to the first SSB. This indication information is used to determine the time domain position and / or frequency domain position of the first time-frequency resource in the downlink bandwidth.

[0131] For example, the bandwidth occupied by the first SSB is preset. The terminal device detects the first SSB based on the preset frequency and the bandwidth occupied by the first SSB. After detecting the first SSB, the terminal device can determine the bandwidth occupied by the first SSB.

[0132] (2) The first SSB carries indication information for determining the first downlink frequency domain unit set.

[0133] For example, the first SSB carries indication information for determining the first downlink frequency domain unit set and indication information for determining the first time-frequency resource. Based on the first SSB, the first downlink frequency domain unit set and the first time-frequency resource in the first downlink frequency domain unit set can be determined.

[0134] For example, the first SSB is used to determine the downlink bandwidth corresponding to the first SSB and the first time-frequency resource within that downlink bandwidth. That is, in this example, the first SSB also includes indication information for determining the downlink bandwidth corresponding to the first SSB.

[0135] For example, the first downlink frequency domain cell set is determined based on the bandwidth occupied by the first SSB. For instance, the first downlink frequency domain cell set is the bandwidth occupied by the first SSB (e.g., both the starting position and the bandwidth size are the same).

[0136] For example, the first SSB includes indication information for determining the first downlink frequency domain cell set. For instance, the indication information carried in the first SSB indicates an offset value between the starting position of the first downlink frequency domain cell set and the starting position of the first SSB. As another example, the indication information carried in the first SSB indicates the size of the first downlink frequency domain cell set.

[0137] (3) There is a mapping relationship between the time-frequency resource where the first SSB is located and the first time-frequency resource, or the first time-frequency resource is determined based on the time-frequency resource where the first SSB is located according to a preset rule.

[0138] For example, the temporal positional relationship between the first time-frequency resource and the time-frequency resource where the first SSB is located is preset or determined by preset rules. Another example is that the bandwidth occupied by the first time-frequency resource is determined based on the bandwidth occupied by the first SSB. For instance, the bandwidth occupied by the first time-frequency resource is the same as the bandwidth occupied by the first SSB (e.g., the starting position and bandwidth size are the same).

[0139] In some embodiments, the first time-frequency resource is a time-frequency resource in a first downlink frequency domain unit set, and the first SSB is used to determine at least one of the following: the time-domain position of the first time-frequency resource in the first downlink frequency domain unit set, the frequency-domain position of the first time-frequency resource in the first downlink frequency domain unit set, the QCL (Quasi Co-Location) relationship corresponding to the first time-frequency resource; and / or, to receive a first system message in the first downlink frequency domain unit set based on the first SSB.

[0140] In some embodiments, the first SSB is used to receive N system messages, including: the first SSB is used to receive a system message, wherein the system message includes a first system message.

[0141] For example, an SSB transport opportunity (or SSB transport set) includes SSB#1 and SSB#2, where SSB#1 is used to receive system message #1 and SSB#2 is used to receive system message #2, wherein system message #1 is used to determine first WUS configuration information and system message #2 is used to determine second WUS configuration information.

[0142] For example, as shown in FIG7, the network device can send SSB#1 and SSB#2, wherein SSB#1 is used to determine a first time-frequency resource, the first time-frequency resource is used to transmit DCI#1, DCI#1 is used to schedule PDSCH#1, and PDSCH#1 carries system message #1; SSB#2 is used to determine a second time-frequency resource, the second time-frequency resource is used to transmit DCI#2, DCI#2 is used to schedule PDSCH#2, and PDSCH#2 carries system message #2.

[0143] In some embodiments, the first SSB is used to receive N system messages, including: the first SSB is used to receive multiple system messages, among which the first system message is included.

[0144] For example, SSB#1 is used to determine two system messages, namely system message #1 and system message #2, wherein system message #1 is used to determine first WUS configuration information and system message #2 is used to determine second WUS configuration information.

The SSB transport opportunity includes two SSBs, namely SSB#1 and SSB#2. Among them, SSB#1 is used to receive system message #1, and SSB#2 is used to receive system message #2.

[0147] In some embodiments, the first system message is also used to determine at least one of the following (1) to (9).

There is a one-to-one correspondence between the N cells and N WUS configuration information. Optionally, the N cells include the first cell, and the WUS configuration information corresponding to the first cell is the first WUS configuration information. For example, if the first cell is in normal operating mode, the first system message does not include the first WUS configuration information; or, if the first cell is in energy-saving mode, the first system message includes the first WUS configuration information.

[0173] In some embodiments, the first uplink frequency domain unit set is the uplink frequency domain unit set in the first cell. Alternatively, the first uplink frequency domain unit set is the uplink frequency domain unit set corresponding to the first downlink frequency domain unit set.

[0174] The following is an introduction to the first WUS configuration information.

[0175] In some embodiments, the first WUS configuration information is used to determine the first WUS resource in the first uplink frequency domain unit set, including: the first WUS configuration information is used to determine at least one of the following (1) to (4).

[0176] (1) The cell identifier of the first cell, wherein the first cell is a cell corresponding to at least one of the following: the first system message, the first WUS configuration information, and the first uplink frequency domain unit set.

[0177] For example, the first WUS configuration information includes the cell identifier of the first cell. For instance, the physical cell identifier of the first cell.

[0178] (2) Information on the first uplink frequency domain unit set.

[0179] In some embodiments, the first uplink frequency domain unit set is an uplink frequency domain unit set used for transmitting and receiving the first WUS. The uplink frequency domain unit set is a set of frequency domain units used for uplink transmission. The uplink frequency domain unit set includes one or more uplink frequency domain units, which are frequency domain units used for uplink transmission.

[0180] For example, the first WUS configuration information is used to determine the list of frequency bands to which the first uplink frequency domain unit set belongs. For instance, the first WUS configuration information is used to indicate the frequency band to which the first uplink frequency domain unit set belongs.

[0181] For example, the first WUS configuration information is used to determine at least one of the following: the start position of the first uplink frequency domain unit set, the end position of the first uplink frequency domain unit set, the number of frequency domain units in the first uplink frequency domain unit set, the number and position of available frequency domain units in the first uplink frequency domain unit set, the number and position of unavailable frequency domain units in the first uplink frequency domain unit set, the offset value, the uplink SCS (Subcarrier Spacing), and the absolute frequency point A. For example, the first WUS configuration information is used to indicate the offset value between the start position of the first uplink frequency domain unit set and the absolute frequency point A, which is determined based on the uplink SCS. As another example, the first WUS configuration information is used to indicate the number of frequency domain units included in the first uplink frequency domain unit set. Based on the above two pieces of information, the terminal device can determine the position and size of the first uplink frequency domain unit set.

[0182] For example, the first WUS configuration information is used to determine the first uplink carrier, and the first uplink frequency domain unit set is the first uplink frequency domain unit set in the first uplink carrier.

[0183] For example, the first WUS configuration information is used to determine the list of frequency bands to which the first uplink carrier belongs. For instance, the first WUS configuration information is used to indicate the frequency band to which the first uplink carrier belongs.

[0184] For example, the first WUS configuration information is used to determine at least one of the following: the starting position of the first uplink carrier, the number of frequency domain units in the first uplink carrier, the carrier offset value, the uplink SCS, and the absolute frequency point A. For instance, the first WUS configuration information indicates the absolute frequency point A, the carrier offset value, and the uplink SCS, and the terminal device can determine the starting position of the first uplink carrier based on this information. As another example, the first WUS configuration information is also used to indicate the number of frequency domain units in the first uplink carrier. The terminal device can determine the bandwidth of the first uplink carrier based on the above information.

[0185] For example, the first WUS configuration information is used to determine the first uplink frequency domain unit set in the first uplink carrier. For instance, the first WUS configuration information is used to indicate the starting position of the first uplink frequency domain unit set in the first uplink carrier (e.g., the offset between the starting position of the first uplink frequency domain unit set and the starting position of the first uplink carrier), the number of frequency domain units included in the first uplink frequency domain unit set, etc.

[0186] (3) Configuration information of the first WUS resource in the first uplink frequency domain unit set.

[0187] For example, the first WUS configuration information includes the configuration information of the first WUS resources in the first uplink frequency domain unit set.

[0188] For example, the first WUS resource can be a resource that appears periodically, or a resource that appears periodically within a period of time, such as a first time window.

[0189] For example, the first WUS configuration information is used to determine the first time window corresponding to the first WUS resource. For instance, the first WUS configuration information is used to indicate the start position and / or length of the first time window.

[0190] (4) Configuration information of the first response resource corresponding to the first WUS resource. The first response resource is used to transmit the first response information, which is the response information corresponding to the first WUS.

[0191] For example, the first response resource is on the first downlink frequency domain unit set.

[0192] For example, the first WUS configuration information indicates the time-domain location and / or frequency-domain location of the first response resource on the first downlink frequency domain unit set.

[0193] For example, the first response resource can be a resource that appears periodically, or a resource that appears periodically over a period of time, such as within a second time window.

[0194] For example, the first WUS configuration information is used to determine the second time window corresponding to the first response resource. For instance, the first WUS configuration information is used to indicate the start position and / or length of the second time window.

[0195] For example, the first response resource can be a resource transmitted via a control channel or a resource transmitted via a shared channel. For instance, if the first response resource is a resource transmitted via a control channel, the first WUS configuration information indicates the configuration information of the search space set and / or the configuration information of the control resource set corresponding to that control channel transmission.

[0196] In some embodiments, the first SSB and the first WUS configuration information correspond to the same cell; or, the first SSB and the first WUS configuration information correspond to different cells.

[0197] In some embodiments, the first SSB is a periodically transmitted channel or signal; and / or, the first system message is periodically transmitted information; and / or, the first WUS resource is a periodically transmitted resource. Exemplarily, the terminal device detects the first SSB and / or the first system message and / or the first WUS resource according to an assumed period. The assumed period can be a predefined period, such as 20ms.

[0198] For example, as shown in FIG8, the first SSB is a periodically transmitted channel or signal with a period of the first SSB period. The terminal device detects the first SSB according to the assumed first SSB period and receives the first system message based on the first SSB.

[0199] In some embodiments, after step 320 above, the following step is further included: the terminal device sends a first WUS based on the first WUS resource.

[0200] The first WUS will be introduced below.

[0201] In some embodiments, the first WUS is used to request the network device to perform at least one of the following (1) to (5).

[0204] In some embodiments, when the first WUS is used to request the network device to send a second SSB, the first WUS configuration information is further used to determine at least one of the following: configuration information of at least one second SSB; transmission start position information of the SSB transmission opportunity corresponding to the second SSB; transmission end position information of the SSB transmission opportunity corresponding to the second SSB; and transmission time window length information of the SSB transmission opportunity corresponding to the second SSB.

[0205] In some embodiments, the configuration information of the second SSB is used to determine at least one of the following (1.1) to (1.6).

[0206] (1.1) The cell identifier corresponding to the second SSB.

[0207] For example, the cell identifier corresponding to the second SSB can be the physical cell identifier corresponding to the second SSB.

[0208] (1.2) The frequency of the SSB transmission opportunity corresponding to the second SSB.

[0209] For example, the frequency point of the SSB transmission opportunity corresponding to the second SSB can be the ARFCN (Absolute Radio Frequency Channel Number) information or GSCN information of the second SSB.

[0210] (1.3) Transmission power information of the second SSB.

[0211] (1.4) SSB index information in the SSB transmission opportunity corresponding to the second SSB.

[0212] For example, the SSB index information in the SSB transmission opportunity corresponding to the second SSB is used to indicate that the SSB transmission opportunity corresponding to the second SSB includes SSB#0 and SSB#1.

[0213] (1.5) Periodic information of the SSB transmission opportunity corresponding to the second SSB.

[0214] For example, the periodicity information of the SSB transmission opportunity corresponding to the second SSB is used to indicate the period of the SSB transmission opportunity corresponding to the second SSB. The starting position of the period of the SSB transmission opportunity corresponding to the second SSB is determined based on the SFN (System Frame Number), such as SFN#0; or, the starting position of the period of the SSB transmission opportunity corresponding to the second SSB is indicated by the first WUS configuration information; or, the starting position of the period of the SSB transmission opportunity corresponding to the second SSB is determined based on the resources of the first WUS transmission; or, the starting position of the period of the SSB transmission opportunity corresponding to the second SSB is determined based on the resources of the response information transmission corresponding to the first WUS.

[0215] For example, the length of the period of the SSB transmission opportunity corresponding to the second SSB is indicated by the first WUS configuration information.

[0216] (1.6) The SCS of the SSB transmission opportunity corresponding to the second SSB.

[0217] For example, the SCS of the SSB transmission opportunity corresponding to the second SSB is indicated by the first WUS configuration information.

[0218] In some embodiments, the transmission start position information of the SSB transmission opportunity corresponding to the second SSB is used to indicate the transmission start position of the SSB transmission opportunity corresponding to the second SSB. The transmission end position information of the SSB transmission opportunity corresponding to the second SSB is used to indicate the transmission end position of the SSB transmission opportunity corresponding to the second SSB. The transmission time window length information of the SSB transmission opportunity corresponding to the second SSB is used to indicate the length of the transmission time window of the SSB transmission opportunity corresponding to the second SSB.

[0219] In some embodiments, when the first WUS is used to request the network device to send a second SSB, the first response information corresponding to the first WUS is used to determine at least one of the following (1.a) to (1.f).

[0220] (1.a) Whether the network device sends a second SSB.

[0221] For example, the first response information includes an identifier of the first WUS. When the terminal device receives this first response information, it indicates that the network device has determined to send the second SSB.

[0222] For example, the first response information includes indication information for indicating whether or not to send the second SSB.

[0223] (1.b) The second SSB that the network device will send.

[0224] For example, each of the at least one second SSB corresponds to a label (e.g., the cells corresponding to the second SSB are numbered sequentially starting from 0), and the first response information is used to determine the label information of the second SSB to be transmitted (i.e., to be transmitted). Alternatively, the first response information is used to determine the cell identifier corresponding to the second SSB to be transmitted. For example, if the cells corresponding to at least one second SSB include cells #0 to #5, and the indication information carried in the first response information indicates cell #2, then the terminal device will detect or receive the second SSB at the frequency point corresponding to the second SSB in cell #2.

[0225] For example, if the first response information does not include this information, the terminal device detects or receives the second SSB on at least one set of frequency points corresponding to the second SSB.

[0226] (1.c) Configuration information of the second SSB that the network device will send.

[0227] (1.d) Transmission start position information of the SSB transmission opportunity corresponding to the second SSB that the network device is about to send.

[0228] (1.e) The transmission end location information of the SSB transmission opportunity corresponding to the second SSB that the network device is about to send.

[0229] (1.f) The length of the transmission time window for the SSB transmission opportunity corresponding to the second SSB that the network device will send.

[0230] In this embodiment, the first WUS resource can correspond to the configuration information of multiple second SSBs. The terminal device can detect or receive the second SSB according to the configuration information of the second SSB indicated by the network device through the WUS configuration information or response information. If the network device does not indicate which specific second SSB to send, the terminal device can detect or receive the second SSB according to the second SSB candidate set configured by the network device.

[0231] In some cases, at least one of the following can be determined directly through the first response information: the configuration information of the second SSB to be sent, the transmission start position of the SSB transmission opportunity corresponding to the second SSB to be sent, the transmission end position of the SSB transmission opportunity corresponding to the second SSB to be sent, and the length of the transmission time window of the SSB transmission opportunity corresponding to the second SSB to be sent.

[0232] For example, as shown in FIG9, the terminal device determines the first WUS resource in the first uplink frequency domain unit set based on the first WUS configuration information, and sends the first WUS using the first WUS resource. After receiving the first WUS, the network device sends first response information in the first downlink frequency domain unit set. The first response information is used to determine the configuration information of the second SSB that the network device will send.

[0233] For example, as shown in FIG10, the terminal device determines the first WUS resource in the first uplink frequency domain unit set based on the first WUS configuration information, and sends the first WUS using the first WUS resource. After receiving the first WUS, the network device sends first response information in the first downlink frequency domain unit set, which is used to determine the frequency point set of the second SSB.

[0234] In some embodiments, the network device may not send the first response information, but instead directly send the SSB transmission opportunity corresponding to the second SSB. Accordingly, after sending the first WUS, the terminal device detects or receives the second SSB on at least one set of frequency points corresponding to the second SSB.

[0235] (2) Send the second SSB of the first cell.

[0236] In some embodiments, when the first WUS is used to request the network device to send the second SSB of the first cell, the first WUS configuration information is also used to determine at least one of the following (2.1) to (2.5).

[0243] For example, the first WUS configuration information indicates the downlink carrier bandwidth of the first cell, and then indicates the second downlink frequency domain unit set.

[0244] The aforementioned second downlink frequency domain cell set is a different downlink frequency domain cell set from the first downlink frequency domain cell set.

[0245] For example, the first response resource may be located on either the first downlink frequency domain unit set or the second downlink frequency domain unit set. For instance, the first WUS configuration information indicates whether the first response resource is located on the first or second downlink frequency domain unit set. As another example, if the second downlink frequency domain unit set is configured, the first response resource is located on the second downlink frequency domain unit set; otherwise, the first response resource is located on the first downlink frequency domain unit set.

[0246] For example, the first WUS configuration information indicates the time-domain location and / or frequency-domain location of the first response resource on the second downlink frequency domain unit set.

[0247] The configuration information of the second SSB is the same as that of the aforementioned second SSB, and will not be repeated here.

After receiving the first WUS, the network device sends first response information in the second downlink frequency domain unit set, which is used to determine the configuration information of the second SSB of the first cell.

[0257] In some embodiments, the network device may not send the first response information, but instead directly send the SSB transmission opportunity corresponding to the second SSB. Accordingly, after sending the first WUS, the terminal device detects or receives the second SSB on the frequency set corresponding to the second SSB in the first cell.

[0258] In some embodiments, the first SSB includes an SSB received by the terminal device based on blind detection. The second SSB includes an SSB received by the terminal device based on auxiliary information.

[0279] (3.b) The network device sends a second system message or paging message through the first downlink frequency domain unit set or the second downlink frequency domain unit set.

[0280] For example, if the network device is configured with control channel transmission resources on the second downlink frequency domain unit set, then the second system message or paging message is sent through the second downlink frequency domain unit set; otherwise, it is sent through the first downlink frequency domain unit set.

[0281] For example, the network device displays an instruction to be transmitted via a second downlink frequency domain unit set or a first downlink frequency domain unit set.

[0292] (4) Communicate on the first cell via the first set of functions or capabilities, or communicate on the first cell via the second set of functions or capabilities.

[0293] For example, as shown in FIG12, the terminal device determines the first WUS resource in the first uplink frequency domain unit set based on the first WUS configuration information, and sends the first WUS using the first WUS resource. After receiving the first WUS, the network device sends first response information in the second downlink frequency domain unit set of the first cell. The first response information is used to determine the control channel transmission resource on the second downlink frequency domain unit set. The control channel transmission resource is used to schedule or transmit the second system message or paging message.

[0294] In some embodiments, when the first WUS is used to request the network device to communicate on the first cell via a first set of functions or capabilities, or via a second set of functions or capabilities on the first cell, or when the first WUS configuration information is dedicated to the first set of functions or capabilities, or when the first WUS configuration information is dedicated to the second set of functions or capabilities, the first WUS configuration information is also used to determine at least one of the following (4.1) to (4.5).

That is, it can be considered that using the first set of functions or capabilities for communication is the default configuration.

[0322] For example, as shown in FIG13, the terminal device determines the first WUS resource in the first uplink frequency domain unit set based on the first WUS configuration information, and sends the first WUS using the first WUS resource. After receiving the first WUS, the network device sends a first response information in the downlink bandwidth of the first cell. The first response information is used to determine whether the network device indicates that it intends to use the first frequency domain unit set or the second frequency domain unit set for communication.

[0329] In summary, the technical solution provided in this application divides the process of a terminal device searching for a cell into the following two steps: First, it searches for a first SSB on a first downlink frequency domain unit set corresponding to a small set of candidate frequency points (e.g., a GSCN set). After finding the first SSB, it obtains cell access assistance information based on the first SSB. Then, based on the cell access assistance information, it receives a second SSB or listens for downlink control information on the corresponding second downlink frequency domain unit set, thereby obtaining the cell's system messages. When the network device enters energy-saving mode (e.g., when the number of terminal devices in the cell is small or the service load is light), it can reduce or not transmit "always-on" signals on the second downlink frequency domain unit set to avoid meaningless energy consumption. When a terminal device needs to receive an "always-on" signal (e.g., when the terminal device needs to receive the cell's system messages), it can send WUS to the network device through uplink WUS resources to request the network device to send an "always-on" signal, which can save network energy consumption and ensure the access performance of the terminal device.
